When Microsoft launched the Windows 8.1 preview version out in the wild in late June, the company put out a warning that many Windows 8 PCs that had Intel's latest 32-bit Atom processors inside could not run the preview build, thanks to an issue with their graphics drivers.

The list of PCs covered by this warning was quite extensive, but earlier this month, Microsoft updated its blog post with some good news: "New drivers are now available for most tablets and PCs running Intel’s newer 32-bit Atom processors and now can install the Windows 8.1 Preview."

Those PCs include the Lenovo ThinkPad Tablet 2, the ASUS VivoTab TF810C, the HP Envy X2, the HP ElitePad 900, and the Samsung ATIV Smart PC. If you own one or more of these products, you can now download some new graphics drivers that should allow you to run the Windows 8.1 preview version.

That's the good news. The bad news is that there is one small holdout. Microsoft states, "Please note that the Fujitsu ARROWS Tab series of tablets are still blocked at this time and we continue to work closely with our partners to resolve this issue." That likely includes the recently released Fujitsu ARROWS Tab Q582/F, which the company claims can "function normally after being immersed in room-temperature tap water to a depth of 1.5 meters for 30 minutes." However, it apparently can't handle a simple OS preview download, at least not yet.
